periodicity of f(x)=-1/5 cos(1/5 x)

periodicity

f (x) = - \frac{1}{5} cos (\frac{1}{5} x)

10 π

Solution steps

Periodicity of

a \cdot cos (b x + c) + d = \frac{periodicity of cos ( x )}{∣ b ∣}

Periodicity of

cos (x)

2 π

= \frac{2 π}{\frac{1}{5}}

Simplify

= 10 π

(0.8) (5.3)

- x^{2} + 2

(6, 1), (1, 3)

f (x) = \frac{7 + x ^{2}}{x + 9}

f (x) = \frac{x ^{2} - 3 x - 28}{x - 7}
